Auch... I came as far as to the loop

	    diag_printf("Invoking constructor @ 0x%08x\n", *p);
        (*p) ();
    }
#endif

And put the diag_printf() there... And it prints 1 address and that's 
it... So, do I understand it right that here it is supposed to call C++ 
constructors?... Oh, no... and already in the first one it crashes... So, 
some C++ internal calling conventions have changed. I am pretty helpless 
in what concerns C++ ABI... Anyone?

Thanks
